Those look like triple-flange Monster Beats tips that can be found on Amazon. They worked really well on the Roxanne II because the nozzle of the Siren earphones are so large in diameter it provides most of the isolation and the flanges pressed down in my ear canal provided that last little bit. However, I don't like them on the Shure IEMs at all. Alone, those tips are too thin to provide me with the necessary sealed ear enclosure for a solid sound. This may just be me. I never could understand how people thought the Westone Star tip or Spinfit were any good. They only produced a shallow undesirable sound in my ears. I always thought that was way people weren't satisfied with the treble response. They weren't getting a solid thick sound. Again, it may just be my ears.
I prefer Shure's own triple flange tip back filled with foam. I think most people are better off with custom tips.
